Marriage of man and wife is Fate itself,
stronger than oaths, and Justice guards its life.
But if one destroys the other and you relent —
no revenge, not a glance in anger — then
I say your manhunt of Orestes is unjust.
— Apollo addressing the Leader, in Aeschylus’s Eumenides, the final play in his Oresteia trilogy (from the translation for Penguin by Robert Fagles, p.240, lines 215-19)
